Installation

!
Please note
Incorrect installation can lead to
collector damage.
Use only gunmetal or brass fit-
tings and copper pipes for the
installation.
Use hemp only in conjunction
with pressure and temperature-
resistant sealants (e.g. Viscotex
Solarpaste from Locher,
CH-9450 Altstätten, Switzer-
land).
Never step on the collectors.
Never solder near or on the col-
lector.
1. Position pipes so that complete ven-
tilation is guaranteed. Install an air
separator at an accessible point in
the pipework (see the following dia-
gram).
2. Equip systems to EN 12975 with an
expansion vessel, safety valve and
circulation pump.
3. The expansion vessel must be
approved to DIN 4807 [or local regu-
lations] and must be installed with a
thermal insulating loop. The dia-
phragms and seals of the expansion
vessel and safety valve must be suit-
able for the heat transfer medium.
To calculate the pre-charge
pressure, see the "Vitosol"
service instructions.
4. When operating without a Solar-Div-
icon, only use safety valves designed
for 120 °C, a maximum pressure of 6
bar, and which carry the "S" (Solar)
designation.
5. Make all connections pressure and
temperature-resistant (observe the
maximum idle temperature of the col-
lector).
